HOUSE-HEATING SYSTEM.

Application filed January 16, 1922. Serial No. 529,420.

'1' all w/mm. it may concern.

lie it known that I, F REDERICK M. MINER, J12, a citizen of the United States, residing at Madison. county of Dane, and State of lVisconsin, have invented certain new and useful Improvements in House-Heating Systems, of which'the following is a specificution, reference being had to the accompanying drawings, forming a part thereof.

The invention relates to heating systems.

In the usual oil-burning heating systems, combustion is carried out at atmospheric pressure or slightly above such pressure. Such systems do not give as high a heat return as may be obtained by generating the heat at relatively high pressures. It Is the object of this invention to generate the heat at high pressure by consuming the fuel in an explosive or constant ressure internal combustion engine in Whic 1 the heat from the cylinders and the exhaust is utilized to produce hot water or steam for a house heat- Ing system, and in this way it Is possible to utilize almost the entire heat output of the engine. Furthermore, when it is desired to run the engine forming the combustion apparatus under load it may be coupled to a generator which furnishes its current to an electrical heating coil in the boiler forming a part of the system.

' With the above and other objects in view, the invention consists in the apparatus hereinafter describedand all equivalents.

The drawing shows an elevation view partly in section of an apparatus embodying the invention.

In the drawin an internal com ustion en 'ne. engine shown is of the exp osive type, a carburetor 2, an oil engine or gas engine ma also be used in this m.

I bloiler 3 is congiected to the jacket space 4ofteengine1 y i 5 as supports for the A heating coil 6 or other suitable system of piping is mounted in the boiler, and its lower section 7 is connected by pipes S to the exhaust I leading from each of the cylinders of e engine, there being four cylinders in the on- K) gine shown. The pipes 8, as well as the the numeral 1 desi ates Whie the pipes 5 and the other pip inthe w mare preferably provided wi suitable heatinsu ati coverings to reduce radiation 11 losses. 'Fhe arrangement of e from the exhaust of each cylin prevents steam 14 formed therein to the radiator 10,

may also be connected u and 13, as will be rea ily understood by .exhaust gases from the which also act I separate pipes back pressure interfering with the proper operation of theengine.

A riser pipe 9 leads from the boiler 3 and a radiator 10 is connected to said pipe by a pipe 11, and a wet return pipe 13 leads to the lower rtion of the water jacket space of the engine. I have shown a steam heating arrangement in which the pipe 9 leads from the top of the boiler to conduct the be used as the heat condesired. Other radiators with the pipes 9 but hot water may veying medium, i

those skilled in this art. I, With this construction the operation of the engine heats u the water in the jacket space, which is in rl irect communication with the water in the boiler 3, so that the heat conducted through the cylinder walls of the engine is used lor heating the water, and as the exhaust gases from the engine discharge into the coil in the boiler the greater proportion of the heat of the exhaust gases is used to heat the water in the boiler.

The remainin available heat in the ex- 7 haust gases, wit the exception of a very small amount, is recovered by passing the coil 6 through a ipe 15 to a radiator 16 and thence through a pipe 17 to the chimney 18, which provides a good draft to carry away the spent exhaust gases. This radiator 16 im arts its heat to the air in the room in whic it may be located by direct radiation.

In some instances where the engine is directly connected to a generator 19, as in a farm lighting plant, or where such generator or other power consuming device is provided for putting a loadon the engine, the current from the generator may be conducted throu h a circuit including an electrically hea resistance element 20 located in the 'i ii be a. b m mg h e stemmay starts ytu to engine ver byjiand or by starting systems now used on automotive vehicles.

I desire it to be understood that this invention is not to be limited to any specific form or arrangement of parts exoe t in so far as such limitations are specifi in the claims. y A

What I claim as my invention is:

1. In a heatin system, the combination of a boiler, a ator, and piping connectno ing said radiator with the boiler,

2. In a heating system, the combination of a boiler, an internal combustion engine, means for conducting the exhaust from said engine through the boiler, a generator driven by the engine, and a current-consuming heating element in circuit with the generator and disposed within the boiler.

3. A heating plant comprising a watercooled multicylinder internal combustion engine, a boiler in circuit with the jacket space of the engine, an exhaust pipe having a coil disposed within the boiler, and separate exhaust pipes from the engine cylinders pass ing into the boiler to conduct the exhaust gases to said coil.

4. A heatin plant comprising a liquid-- cooled multicy inder internal combustion engine, a boiler, pipin supporting the boiler above the engine an establishing communication between the boiler and the jaelret space ofthe engine, an exhaust pipe having a coil disposed within the boiler, and separate exhaust pipes from the engine cylinders passing into the boiler to conduct the exhaust gases to the coil.

5. In a heating system, the combination of a boiler, an'internal combustion engine, means for conducting the exhaust from said engine through the boiler, a power-consuming device driven by the engine, and"means for converting the energy of said device into heat energy supplied to the boiler.

6. In a heating system, the combination of a boiler, an internal combustion engine having its jacket space communicating with the boiler, means for conductin the exhaust from said engine throu h t e boiler, a power-consuming device riven by the engine and means for converting the energy of said device into heat energy supplied to the boiler whereby the entire output of the engine and the heat of the exhaust and jacket is utilized to supply heat energy to the boiler.
